Does anyone know why some images cannot be uploaded and get the error "Your attachment has failed security checks and cannot be uploaded. Please consult the forum administrator."? I tried to attach 3 images to a post yesterday and got that error. I thought it was something with the wifi where I was at, so I tried again today. No dice - still got the same error. Why am I getting it, and is there anything I can do to fix it? The images comply with the stated file size limitations, so I don't know what else it could be.
